<p>PURPOSE: To provide a sagging level measurement device for an aerial wire with which stable measurement is obtained without depending on a measuring person and site condition. CONSTITUTION: Relating to a device which measures the degree of sagging of an aerial wire stretched between two supporting points, a traveling device 1 which travels on the aerial wire is provided, and on the traveling device 1, a travel distance meter 12 measuring travel range and an inclinometer 13 for measuring inclination against horizontal plane are mounted, and, based on these travel distance and inclination, a current position of the traveling device 1, in a coordinate system whose origin is one supporting point, is found, and the degree of sagging is found from the current position.</p> |
